Clinical Value of Routine Biomarkers for Colorectal Patients: a Retrospective Study.

Background: Colorectal cancer (CRC) has always been one of the most common malignant tumors in the world. Whether the factors related to the diagnosis and risk of CRC can be found from the existing peripheral blood routine indicators.

Methods: The relevant data of patients with colorectal diseases in our hospital of about ten years were collected, the differences among the biomarkers in serum were analyzed, the risk factors were analyzed by logistic regression, the ROC was drawn, and the diagnostic efficacy was evaluated.

Results: Colorectal malignancies and benign diseases in AST, GGT, LDH, D-BIL, ALB, ALP, AchE, CR, TP, PA, RDW, LMR, NMR, TC, TG, HDL-C, CA19-9, CEA, Cyfra21-1, and Fer have statistical differences (p < 0.05). ALB, PLR, CEA, Fer, NLR, TP, GGT, and Cyfra21-1 in different malignant tumor types have statistical differences (p < 0.05). When CEA increased by 1, the risk of colorectal cancer increased by 45.7%. When AchE and HDL-C increased by 1, the risk of colorectal cancer decreased by 32% and 66.8%. Compared with other blood groups, blood group AB colorectal cancer patients had a shallower tumor invasion (p = 0.047). HDL-C were significantly weakly-correlated with tumor size (p < 0.05, |r| < 0.4). CEA, AchE, and HDL-C were combined diagnosed; the sensitivity, PPV, and accuracy were 94.35%, 95.43%, 90.77%, respectively.

Conclusions: The occurrence and development of colorectal cancer is the result of multi-factors, and the combined detection of multi-indicators has positive significance for the diagnosis, pathological stage, and prevention of CRC.
